The invention discloses a vertical shaft type gravity energy storage equipment resistance reduction device which comprises a flow guide cover arranged at the upper end and/or the lower end of a lift car body, and the shape of the flow guide cover is gradually reduced in the direction away from the lift car body; the outer side face of the flow guide cover comprises two adjustable shutter type air guide plates which are oppositely arranged, a left suction fan, a right suction fan and a front end suction fan are arranged in the flow guide cover, and the left suction fan and the right suction fan are close to the two adjustable shutter type air guide plates respectively. The front-end suction fan is located on the sides, away from the lift car body, of the leftward suction fan and the rightward suction fan and corresponds to the position between the leftward suction fan and the rightward suction fan, and the end, away from the lift car body, of the flow guide cover is provided with a front baffle capable of being opened and closed. According to the scheme, the air pressure difference between the top wall and the bottom wall in the operation process of the lift car body can be effectively reduced, the flow separation phenomenon near the lift car body is greatly restrained, and therefore the purpose of reducing air resistance borne by the lift car in the operation process is achieved.
本发明公开一种竖井式重力储能设备减阻装置,包括有在轿厢本体上端和/或下端设置的导流罩,导流罩的形状呈在远离轿厢本体的方向上逐渐变小;导流罩的外侧面包括有两个相对设置的可调百叶窗式导风板,在导流罩内设置有左向吸风机、右向吸风机和前端吸风机,左向吸风机和右向吸风机分别靠近两个可调百叶窗式导风板,前端吸风机位于左向吸风机和右向吸风机远离轿厢本体的一侧且对应于左向吸风机和右向吸风机之间的位置,导流罩在远离轿厢本体的一端具有可开闭的前挡板。本方案能够有效地减少轿厢本体在运行过程中顶壁与底壁之间的空气压强差,极大地抑制了轿厢本体附近的流动分离现象,从而达到降低轿厢在运行过程中所受到的空气阻力的目的。
